SPECIFICATION forming part of Letters Patent No. 324,349, dated August18, 1885.

Application tiled October 11I 1883. (No model.)

To all whom, it may con/cern.-

Be it known that I, ALois ALTMANN, a citizen' ofthe United States,residing at Manitowoc, in the county of Manitowoc and State ofWisconsin, have invented certain new and useful Improvements inMattresses; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form apart of thisspecification. l

, My invention relates to improvements in mattresses; and it pertains tothat class which may be taken apart and packed in a small space forshipping.

My invention is explained by reference to the accompanying drawings, inwhich- Figure 1` represents a side view. Fig. 2 represents a top view.Fig. 3 represents an end view, and Fig. 4 a detail.

Like parts are represented by the same reference-letters throughout theseveral views.

A A are the side bars of the frame, which are rigidly connected togetherby the crossbars B B B B, the ends of which cross-bars B are secured tosaid bars by dovetail joints C O, (shown in Fig. 1,) land joints D D,(shown in Fig. 2.) The series of slats E E are supported above the frameformed by the side rails and cross-bars bythe four corner-posts E E uponthe rounds G G. The ends of the rounds G G are loosely fitted in theirbearings in the posts E', and adapted to turn-slightly therein as thecenters of the slats E spring up and down. The centers of the slats aresupported by spiral springs H H. The upper and lower ends of thespringsH are kept in place by the 4o short studs I. The upper studs Iare permanently attached to the cross-pieces J J, while the lower studsare attached to the cross-rails B. The cross-pieces J are attached totwo of the spring-slats E, as shown, by bolts K.

When desirous, the cross-rails B B are detached from the side rails, A,when the slats are disconnected from the frame by withdrawing the roundsG G from the posts E', when said parts may be putup in a compact shapefor shipping.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is-

Vl. The combination of the mattress-frame consisting of side rails andcrossbars, cornerpost-s E E E E', rounds G G, series oflongitudinallyarranged elastic slats E E, secured at or near their endsto rounds G G, and central supporting spiral springs H, allsubstantially as and for the purpose specified.

2. The combination of the side rails, A A, detachable cross-bars B B andC O, posts E E E E', rounds G, tted to turn in the upper ends of saidposts, series of elastic slats E E, cross-bars J J, and spiral springsH, interposed between said bars J J and bars B B, all substantially asand for the purpose speciiied.

In testimony whereof I affix my signature in presence of two witnesses.
